.Sh DESCRIPTION
.\" ------------------------------------------------------------------
RabbitMQ is an open source multi-protocol messaging broker.
.Pp
Running
.Nm
will attempt to discover and echo the process id (PID) of the Erlang
runtime process
.Pq Pa erl.exe
that is hosting RabbitMQ.
To allow
.Pa erl.exe
time to start up and load RabbitMQ, the script will wait for ten seconds
before timing out if a suitable PID cannot be found.
.Pp
If a PID is discovered, the script will echo it to stdout
before exiting with a
.Ev ERRORLEVEL
of 0.
If no PID is discovered before the timeout, nothing is written to stdout
and the script exits setting
.Ev ERRORLEVEL
to 1.
.Pp
Note that this script only exists on Windows due to the need to wait for
.Pa erl.exe
and possibly time-out.
To obtain the PID on Unix set
.Ev RABBITMQ_PID_FILE
before starting
.Xr rabbitmq-server 8
and do not use
.Fl detached .
